Well yeah I agree with you about Beb bc of her intelligence use of magic, but I’d consider Kernel a mixed member of Ravenclaw and Slytherin. Not bc I think he’s a bad or ambitious guy, but bc of his introverted and special influencal personality. I dunno I just think members of Slythrin are smarter than Griffendor’s.
And I kinna consider Grubbs a Griffy. He’s got a more typical magical personality than the other two.
